.WI'L 1AM Kon'r To all sha om i Be it known that Win11 citizen of; the United] Sta Kingston, in the co inty of UlsterahdState wand of New Yorlr, haveinvented certain ne useful Improvements in Non ltefi tainers, of whichthe specifica tion.

able containers, and has for anob at to CH m.- vlde a container of this nature having Us 1 ner surface corrugated, and embodying a movable bottom which is moved toward the orifice of the container as the contents thereof are withdrawn, said bottom being formed in a manner to preclude its return to the bottom of the container, therebyeffe tively terial.

A still further object of the inventionis to provide a non-refillable container of the nature above set forth, which comprises few parts and those of a simple nature, insuring positive action and permitting its manufac ture at a reduced cost.

In addition to the foregoing, this invention colnprehends improvements in the details of construction and arrangement of parts, to be hereinafter described and particularly pointed out in the appended claim.

In the accompanying drawings, in which similar and corresponding parts are designated by the same characters of reference,

throughout the several views in which they appear: 1

Figure 1 is a view in side elevationwith parts broken away, to show details.

Fig. 2 is a view in edge elevation of the parts of the movable bottom 1n dissociated relation, and

Fig. 3 is a View of thebottom 1n plan. With reference to the drawings, 10 indicates a cylindrical container, open at its bottom end and tapering abruptly at its other end to form a. neck 11 which is threaded externally as at 12 to engage a complemental internally threaded cap 13 having a spout lt formed therewith.

The open or bottom lend is thickened as at 15 with a portion of its surface formed smooth and parallel to the walls of the container to form a valve seat as at16. The thickened portion is then tapered toward the bottom toform a conical entrance for the container as indicated at 17.

e 8 having afboss formed inte on at one side, and its periphery cn'cumferentially as" at 20," the boss dicated at 19 and the groove at 19. e 20, is formed right 'angularly, greet/e19 curved transversely,

or'concai ed."* A packing "ring 21 of cork or ;other u tablematerial is applied to the boss ov bl'e"bottonnhaving its inner pcp y curved transversely to fit the groove 19. The inner surfaceof the container is formed with circumferential ridges or ribs 10"which are directed toward the lower end or mouth of the container for a purpose whichfwillflbe presently apparent. p

Inassembling the bottom inthe container a wire ring22 is engaged in the groove 20' of the bottom, whereby, when the bottom is inserted in the open end of the container the ring, which is split to permit its diameter to bevaried, is first contracted and then eX- panded soias to engagethe inner wall of the f container andbecome seated between adjacent ribs 10 while still engaged within the groove 20 of the bottom, thereby preventing Withdrawal of the bottom. The packing ring 21 being compressible permits itself to be forced into the constricted end of the con- .tainer,the ring subsequently expanding and tightly engaging the wall of the container.

In an initial position of the bottom the periphery thereof should be seated against the valveseat 16 of the thickened portion of thecontainer to form a seal to insure the retention of the contents therein. As shown in Fig. 1,: the ring 22 is of such a size as to exactly lie over the union of said bottom 18 and the container, thereby insuring a liquid tight connection between said bottom and container.

I11 use, the contents ofthe container is discharged by inverting the same whereupon, the movable bottom is pressed toward the mouth by the finger and the contents forced through the spout 14L.

After the container is empty, it will be obvious the movable bottom cannot be restored to its former position since the the same being in an m: 171

smooth under surface affords no opportunity 1 to apply a tool thereto. Furthermore, if a tool or air pressure is introduced into the mouth ofthe container for the purpose of 1 moving the bottom member, ribs 10 on the inner wall of the container will absolutely prevent downward movement of the follower, owing to the secure manner in which the r1ng'22 is engaged against the ribs;

I Having thus described my invention,lwhat I claim as new and desire to secure Letters Patent is:

A device of the class described, including a cylindrical container open at its bottom and tapering abruptly at .its other ,end .to form a neck, said bottom beingthickened with its surface formed smooth and parallel to the walls ofsaid container to provide a valve seat said thickened portion tapering toward the bottom. to form a conical entrance, the inner surface of said container being formed with. circumferential sharp edged ribs directed toward the lower endgof said container, a removable disk shaped bot:

Copies of this patent may be obtained tom with a' circumferentially grooved boss, formed on one side, said bottom having a circumferential groove, said bottom being adapted to fit on said seat a compressible packing ring held in said groove, and a split wire ring held in said bottom groove arrangedto engage the inner wall of said container said ring being of such a size as to lie over the union of said bottom and container,
